STAY ROD AND CHAIN FOR VEHICLES.

SPECIFICATXON forming part of Letters Patent No. 640,243, dated January 2, 1900.

Application filed May 10, 1899. Serial No. 716,321. (No modelo and operation of this portion of the runninggear of vehicles.

1I/'ith this object in view my invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specifically pointed out in the claims.

In order to enable others skilled in the art to which my invention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation, reference being had to the accompanying drawings, forming part hereof, in whichf- Figure 1 is a bottom plan view of the runninggear of a wagon having -my invention applied thereto. Fig. 2 is a detail view, on an enlarged scale, of the attachments for the front axle. Fig. 3 :is a view in side elevation of the middle part of the coupling-pole and its connections.

Like numerals of reference mark the same parts in all of the figures of the drawings.

Referring to the drawings by numerals, 4 indicates the rear axle, 5 5 the rear wheels, 6 the rear hounds, '7 the coupling-pole, 8 the front hounds, 9 the front axle, 10 10 the front wheels, 11 the sand-bolster of the front axle, and 12 the doubletree, all of which may be of any ordinary orapproved construction and form no part of my invention.

To the under side of the front axle are secured two bars of iron 13, one near each wheel and each provided with front and rear hooks. To the front hook ot' each bar is engaged a link 14, which at its front end engages in a hole in 'the outer end of a lever-bar 15. A similar link 16 connects a rear leverbar 17 with each rear hook of the bars 13, and each pair of lever-bars 15 and 17 are connected at their inner ends by a rod 18, passing between two bolts 19, projecting from the sandbolster. Each lever-bar 15 is coupled t0 the outer end of the doubletree 12 by a rod or chain 20, connected to the center of the leverbar.

2lindicates a bracket-bar secured to the coupling-pole 7 and extending in front of and behind the point of junction of the hounds with the coupling-pole. A grooved pulley 22 is mounted between bar 21 and the coupling pole on a pin 23, passing through the bar and pole.

A chain or combination of chains and rods, as at 24, is connected at one end to the center of one of the lever-bars 17 and at the other end to the center of the other lever-bar 17, passing around the pulley 22. The pulley may be made of wood faced with metal or of all iron or steel, as may be desired, and there may be chains or rods used, as may be desired, wherever either will work. The posit-ion of the pulleyon the pole may be changed toward the front or rear, if desired.

In the practical operation of my invention when a wheel strikes an obstruction it will not stop and the opposite wheel will not run forward, and as a consequence the tongue will not jump from one side to the other. The stays should be tight, and the wagon may be turned as short as possible, and while turning the effect will be the same as when pulling forward, provided both horses are pulling. The lever-bars permit one horse to pull ahead of the other and yet pull only his share of the load, and the wheels will pass over obstructions just the same as though both horses were pulling even with each other.

While I have illustrated and described what I consider to be the best known means for car rying out my invention, I do not wish to be understood as restricting myself to the exact forms and constructions shown,as many slight changes therein or variations therefrom mightl'g 5 IOO of the axle linked to the axle, attheir oute'r ends, and 'co'iireeted tothe doubletree at their centers, with a pulley journaled on the coupling-pole behind the axle and connections between the inner ends of the lever-bars passing around the pulley, substantially as described.

2. In a vehicle running-gear, the combination with the rear axle, coupling-pole and doubletree, of a lever-bar in rear of each end of the axle and linked to the axle at their outer ends, and connected to the doubletree at their centers, with a pullef,7 journaled on the coupling-pole behind the axle and connections between the inner ends of the lever-bars passing around the pulley, substantially as described. p

3. In fa vehicle running-bear, the combination with the front axle, coupling-pole, and doubletree, of lever-bars in front and rear of the axle near each end, linked to the `axle at their outer ends and linked together 'at their inner ends, connections between vthe center f veach front lever-bar and the ends of the doubletree, a lpulley journaled on the vcoupling-,pole behind lthe axle' and a flexible connection between the centers of ythe rear leverbars passing around the pulley, substantially as described. v v

4. In a vehicle running-gear, the combination with the front axle, doubletree and couplin g-pole, of two bars having hooked front and `rear ends, one bar being secured to the axle
